How to Stop a Windshield Crack from Spreading

February 13, 2025 | Auto Expertise, Mobile Windshield Chip Repair Service |


To prevent a windshield crack from spreading, avoid sudden temperature changes, minimize vibrations, and get professional repair as soon as possible. In Denver’s extreme weather conditions, immediate action is crucial to avoid costly replacements.

Why Windshield Cracks Spread Faster in Colorado

Colorado’s freeze-thaw cycle, high altitude, and road debris make windshield cracks worsen more quickly than in milder climates. Key factors include:

  • Temperature Fluctuations: Sudden weather changes cause glass to expand and contract, making cracks spread.
  • Altitude Pressure: Colorado’s high elevation increases pressure on cracked windshields.
  • Road Debris & Gravel: Icy roads in winter mean more loose gravel and debris hitting windshields.
  • Snow & Ice Removal: Using hot water or a defroster on a cold windshield can cause immediate cracking.
  • UV Exposure: Colorado’s higher UV levels weaken the windshield over time, accelerating crack growth.

Signs Your Windshield Crack Is Getting Worse

  • The crack is expanding daily.
  • You notice spiderwebbing (small cracks branching out).
  • The crack is near the edges of the windshield.
  • You hear popping sounds while driving.
  • Dirt and moisture are accumulating inside the crack, making it more visible.

Best Practices to Prevent a Windshield Crack from Spreading

1. Schedule a Professional Repair Immediately

  • Addressing the issue early can save you from costly replacements.
  • Professional windshield chip and crack repairs use resin injection technology to stabilize the crack and prevent further damage.

2. Avoid Sudden Temperature Changes

  • DO NOT pour hot water on a frozen windshield.
  • DO NOT blast defrosters directly onto the crack.
  • Park in a garage or shaded area to minimize glass expansion.
  • Use a windshield sunshade in the summer to reduce UV damage.

3. Drive Carefully & Minimize Vibrations

  • Avoid potholes and rough roads.
  • Close car doors gently to prevent added pressure.
  • Avoid slamming on brakes suddenly, which can increase windshield stress.

4. Keep the Crack Clean & Dry

  • Moisture and dirt can seep into the crack, weakening the glass.

If you can’t get an immediate repair, protect the crack from dust and moisture with a temporary barrier.
